针对点云数据局部集中的特点,使用差值预测对点云数据进行预测处理 在预测的同时,根据IEEE2754
浮点数标准,简化浮点数的尾数,使用3. 5 Byte来表示一个浮点数,以提高压缩效果 然后对预测数据中连续重
复的字节使用该字节加该字节重复的次数的方式存储 最后对经过以上处理的数据使用一阶自适应算术编码进
行压缩。最终得到的程序在压缩比和内存占用两个方面远优于WinRAR、WinZip压缩软件-Point cloud data for the characteristics of l

The digital baseband predistorter is an effective technique to compensate for the nonlinearity of
power amplifiers (PAs) with memory effects. However, most available adaptive predistorters based on direct
learning architectures suffer from slow c
